Abstract

Provided herein are ecologically friendly waterproof fabrics that include a base fabric having a body-facing surface and an outward-facing surface, and a hydrophobic, waterproof barrier disposed on the outward-facing surface of the base fabric. The base fabric may be a wicking fabric or may be treated with a compound that enhances wicking, and the hydrophobic, waterproof barrier may include a plastic polymer, polyurethane, polyethylene, and/or polytetrafluoroethylene. The waterproof fabrics also may include an abrasion-resistant coating and/or a PFC-free durable water repellant (DWR) agent disposed on an outward-facing surface of the hydrophobic, waterproof barrier, and one or both of the abrasion-resistant coating and/or PFC-free DWR agent may be discontinuous. Also provided are methods of making a waterproof fabric.
